Layered Double Hydroxides as Nitrate Adsorbents in Water and Their Incorporation into Alginate Hydrogels Using Various Techniques
Nitrate contamination of water is a growing issue due to agricultural practices, industrial activities, and the natural characteristics of water sources. Hydrotalcites, or layered double hydroxides (LDHs), are effective adsorbents for contaminants such as nitrates. In this study, hydrogels incorporating LDHs were developed to create filters for water remediation. Synthesis, characterization, and nitrate removal tests were performed, achieving good results in both simulated and real water.
